"David replaced our old water heater with an efficient heater that saved us hundreds of dollars. He was friendly and very respectful as he explained our issue and how he would solve it. Ps. David also removed our old water heater with no problem. He did the entire job in a timely manner."

"When something breaks that you have no experience with, you're doing more than just looking for someone that will fix it. You're putting your faith into someone to do the job and at the same time not take you for a ride for all you're worth. Mark was that professional for us when our water heater went. He was knowledgeable, skilled, and his rates were very reasonable compared to others. It was a pretty extensive job. Mark ended up installing a combination water heater and boiler unit to replace the broken system and our ancient boiler. He left our basement better than when he started. We definitely recommend him and will be returning to him for future projects."

"Not only did Jason do an awesome job replacing our leaking water heater, he was also extremely fast. He was done faster than we could even miss the temporarily missing hot water. Jason was also very punctual, both for our estimate and for the replacement. He also gave us multiple options to fit our budget so that was a great plus. Will be calling him again for the inevitable plumbing issues!"

"Having experienced trades people who do not show up on time or complete work, it was refreshing to find a company that offers excellent customer service. The needed work was scheduled for the next day. We were kept informed of the anticipated arrival time. Once at our home, we were apprised of what work would be required. John and Zack went above and beyond by helping us with an additional plumbing job after competely completing the needed repair. John also alerted us to a situation that, if left uncorrected, will be a costly repair. At no point did he pressure us or try to take advantage of the situation. We believe John was simply providing us with good service and at a reasonable cost. We also noticed John interacted with his employee, in a respectful manner. It was obvious to us that John was mentoring his employee and imparting his knowledge in a manner that reflected his pride in his chosen profession. We recommend Newburgh Plumbing without reservation and are happy to know that there are still trades people who care about the work they do and want to provide high quality services for their customers. Kudos to John, Zack and the woman who scheduled the appointment."

FAQs for water heater repair or service projects in Cornwall, NY

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
